Study Notes
Introduction to Human Anatomy
- Human anatomy is the study of the structure of the human body, its parts, and their relationships.
- It encompasses detailed examination of cells, tissues, organs, and systems within the organism.
- Understanding how the body functions, diagnosing diseases, and guiding surgical procedures are crucial applications.
Anatomical Terminology
- Standardized language for describing body structures, positions, and directions.
- Precise terms avoid ambiguity.
- Examples: anterior (front), posterior (back), superior (above), inferior (below).
- Key directional terms relate to anatomical position (standing upright, facing forward, arms at sides, palms forward).
- Planes of sectioning aid in visualizing internal structures (e.g., sagittal, coronal, transverse).
Body Cavities
- Enclosed spaces within the body that house and protect internal organs.
- Dorsal cavity contains the brain and spinal cord.
- Ventral cavity contains the thoracic cavity (lungs, heart) and the abdominopelvic cavity (stomach, intestines, reproductive organs).
- Membranes lining these cavities reduce friction during organ movement.
Cell Structure and Tissues
- Cells are the basic structural and functional units of the body.
- Different cell types specialize in various functions.
- Four primary tissue types: epithelial (covering), connective (support), muscle (movement), and nervous (control).
- Epithelial tissues form linings of surfaces and glands.
- Connective tissues, like bone and cartilage, provide support.
- Muscle tissues contract to enable movement.
- Nervous tissue transmits nerve impulses for communication.
Skeletal System
- Provides support, protection, and movement.
- Made up of bones, cartilages, ligaments, and joints.
- Provides framework for the body.
- Crucial role in blood cell production (hematopoiesis).
- Skeletal system protects internal organs.
- Attachment points for skeletal muscles.
Muscular System
- Responsible for movement in the body.
- Made up of skeletal, smooth, and cardiac muscles.
- Skeletal muscles are voluntary and responsible for locomotion and posture.
- Smooth muscles are involuntary and control internal organs.
- Cardiac muscle is involuntary and found only in the heart.
- Muscle contraction involves protein interactions.
Nervous System
- Consists of the brain, spinal cord, and nerves.
- Transmits signals throughout the body for communication and coordination.
- Central Nervous System (CNS) includes the brain and spinal cord; Peripheral Nervous System (PNS) comprises peripheral nerves.
- Sensory and motor neurons transmit stimuli.
Cardiovascular System
- Composed of the heart, blood vessels (arteries, veins, capillaries), and blood.
- Pumps blood throughout the body delivering oxygen and nutrients to tissues.
- Removes waste products.
- Heart's function is crucial for circulation.
Respiratory System
- Responsible for gas exchange (oxygen and carbon dioxide).
- Involves the lungs, trachea, bronchi, and other structures.
- Mechanism of breathing facilitates oxygen intake and carbon dioxide removal.
Digestive System
- Consists of organs involved in processing and absorbing nutrients.
- Includes mouth, esophagus, stomach, intestines, liver, pancreas.
- Breaks down food for absorption into the bloodstream.
Urinary System
- Responsible for filtering blood and eliminating waste products.
- Includes kidneys, ureters, bladder, urethra.
Endocrine System
- Composed of glands that secrete hormones.
- Regulates various bodily functions like metabolism, growth, and reproduction.
Reproductive System
- Responsible for reproduction.
- Male and female reproductive systems have distinct structures and functions.
Integumentary System
- Composed of skin, hair, and nails.
- Provides protection against environmental factors and plays a role in temperature regulation.
- Skin houses sensory receptors.
